Embodiment

As in accompanying drawing quote, identical reference number is used to indicate identical parts.In the following description, different operating parameters and parts are described for heteroid embodiment.These concrete parameters and parts comprise as an example be not intended to restriction.

In one or more embodiments, advantage of the present utility model is at least to provide two rank force pushing type rivet fastener, it is with the head expanded and the afterbody selectively expanded relative to main body, main body has the first and second shoulders be designed to different axial surface angles, makes from mounting point to working position or the accident of pre-installed position and/or unwanted disengaging can be prevented from.In addition, the head of expansion and afterbody stop pin to any excessive insertion of packing ring further or depart from from packing ring.These parts all time very important operationally assist in ensuring that the usability of the improvement of rivet fastener.

Fig. 1 describes according to the cardinal principle of the one or more embodiment of the utility model with the stereogram of the fastening piece shown in 100 illustratively, and this fastening piece 100 comprises the packing ring 120 limiting opening 122 and the pin 140 be partly contained in opening 122.Packing ring 120 comprises supporting portion 102 and leg 108.The main part 204 that pin 140 comprises head 202, afterbody 206 and is positioned between head and afterbody 202,206.

Fig. 2 A describes the viewgraph of cross-section of fastening piece 100 when being positioned at the first pre-installed position quoted in Fig. 1 illustratively.Head 202 and each outer circumference with the maximum outer circumference being greater than main part 204 of afterbody 206.Term " girth " is in this article in order to refer to the linear range at the edge of the closed curve around a shape, and wherein this shape can be circle, ellipse, square, rectangle or other any suitable shapes.This structure is considered to be of value to and reduces and eliminate the possibility be not supposed to as follows, that is, head 202 inwardly or is downwards unexpectedly forced through opening 122 or main part 204 and outwards or is upwards unexpectedly pulled out together with afterbody 206 and depart from opening 122 completely.When the cross section linear dimension " L1 " of head 202 and the cross section linear dimension " L3 " of leg 206 are greater than cross section linear dimension " L2 " of main part 204, this structure can be implemented.Alternately, when " L1 " and " L3 " is both greater than cross section linear dimension " L4 " of opening 122, this structure can be implemented.

In pin 140 and packing ring 120, whole or its any part of each can be any suitable shape and size.Only for simple and clear object, pin 140 and packing ring 120 are described to circle or ellipse.

In addition as shown in Figure 2 A, pin 140 can comprise flank 205 further to stop unnecessary the subsiding of leg 108.Flank 205 is positioned in the downstream of head 202 and can be close to the supporting portion 102 of packing ring 120, makes the opening 122 that limited by supporting portion 102 and leg 108 under the use of flank 205, be effectively blocked unwanted subsiding.

Referring again to Fig. 2 A, main part 204 comprises the first shoulder 208 and the second shoulder 210 of location adjacent one another are, and both all can be contained in opening 122.In the pre-installed position that such as Fig. 2 A describes illustratively, the finger tip portion 118 of leg 108 can be supported on afterbody 206.On the contrary, afterbody 206 is by contact with finger tip portion 118 direct and the good resistivity in finger tip portion 118 stops and unexpectedly departs from packing ring 120.In a particular embodiment, and in fig. 2, this directly contact realized by contact area 128, contact area 128 comprises and leaves supporting portion 102 and be positioned at most distal point on leg 108 or most end end points (not shown).In such configuration, contact area 128 is rendered as the convex outer surface in finger tip portion 118.

In a particular embodiment, and further in fig. 2b, afterbody 206 comprises tail surface 206a and leg 108 comprises surface, finger tip portion 138, and two surperficial 206a on the cross section that all cross sections are as shown in Figure 2 B given and 138 limit angle " α ", and angle α is acute angle.

Alternatively, sharp angle α can refer to the difference between angle α 1 and angle α 2 further, and wherein angle α 1 can be limited by tail surface 206a based on central longitudinal axis " X "; And angle α 2 can be limited by surface, finger tip portion 138 based on central longitudinal axis " X ".In a particular embodiment, angle α or the difference between angle α 1 and α 2 are not more than 25 °, 20 ° or 15 °.This is favourable, at least because the afterbody 206 of pin 140 is by relatively large surface area instead of may to be out of shape and the single sharp edge forever opened in time contacts with finger tip portion 118.

When angle α is not more than 10 °, 5 ° or 1 °, this benefit can increase further.In this refers to that realizing maximum possible between afterbody 206 and the surface in finger tip portion 118 contacts.When this position, afterbody 206 becomes the smooth frame on the surface providing the contact surface 138 being parallel to finger tip portion 118 fully.Therefore, the afterbody 206 being form with smooth frame reduces any unwanted disengaging between pin 140 and packing ring 120 further.This is useful, is because the larger surface area existed now for the bottom of pin is for contact, instead of can be out of shape and the single sharp edge forever opened in time.This benefit is to provide hard backstop, and it stops the bottom of pin 140 to be pushed through the bottom of packing ring 120 and anti-shotpin 140 and packing ring 120 depart from prematurely or unnecessarily.

In addition, the steering force that pushing pin 140 enters needed for packing ring 120 can be controlled, and makes pin 140 unload from the accident of packing ring 120 or discharge and is effectively blocked by relatively large contact area.When fastening project required with the strict time tolerance, the disengaging (such as pin 140 departs from from packing ring 120) of the parts of unwanted fastening piece may be the thing that operator least wishes to process.The design can help to solve this situation.

Fig. 3 describes the viewgraph of cross-section of fastening piece 100 when being positioned at mounting point quoted in Fig. 1 illustratively.From the pre-installed position shown in Fig. 2 A, pin 140 is promoted by the finger tip portion 118 towards packing ring 120.Due to downward promotion, finger tip portion 118 relatively moves up together with remaining part of leg 108.In movement upwards, finger tip portion 118 is moved across the second shoulder 210 and arrives the first neck 215 be limited between the first and second shoulders 208,210.In a nonrestrictive example, the first neck 215 has the girth larger than the second neck 315 between afterbody 206 and the second shoulder 210.By leg 108 being placed in the first neck 215, leg 108 now stress deformation and leave common longitudinal axis " X " at installed position and outwards launch.

In addition, as Fig. 4 describes illustratively, the head 202 of pin 140 holds through groove 106 and by base plate 306 backstop of groove 106, the head 202 that its further groove 106 and base plate 306 thereof are both limited to avoid selling during use by supporting portion 102 and the leg 108 of packing ring 120 is by mistake touched or promotes.

Fig. 4 describes the viewgraph of cross-section of fastening piece 100 when being positioned at the 3rd working position quoted in Fig. 1 illustratively.As shown in Figure 4, pin 140 is promoted further from the mounting point shown in Fig. 3, makes the leg 108 of packing ring 120 leave the first neck 215 and crosses the first shoulder 208 to be placed in the region between the first shoulder 208 of pin 140 and head 202.In this working position, leg 108 returns back to comparatively small deformation state or its original state.

Fig. 2 C describes the first shoulder 208 of pin 140 as Fig. 2 A, Fig. 3 and Fig. 4 describe illustratively and the zoomed-in view of the second shoulder 210 illustratively.First shoulder 208 is described to comprise the first inclined-plane 207 and the second inclined-plane 209 and is therefore limited by the first inclined-plane 207 and the second inclined-plane 209.Both first and second inclined-planes 207,209 all can arrive the first stopping end 214.In a particular embodiment, first stops end 214 can be reduced to the line replacing visibility region.When being configured to this region, first stops end 214 to be considered to the wearing and tearing that can help when leg 108 moves through the first shoulder 208 to reduce leg 108.

In a particular embodiment, the first and second inclined-planes 207 and 209 can adopt any suitable surface modification.Such as, the first inclined-plane 207 and/or the second inclined-plane 209 can partly comprise concave shape or convex shape, maybe can comprise specific roughness to provide the frictional force of enhancing.The frictional force that application strengthens is with the power of change relative to the expectation of the balance between the easy degree of packing ring 120 moving pin 140 and the obstruction of resisting unwanted motion between operating position.

Second shoulder 210 can comprise such as surface 211,213 with 217 surface and perform and the function similar relative to the first shoulder 208.

In limiting examples and as illustrated illustratively in Fig. 2 C, in first inclined-plane 209, inclined-plane 207, second, the 3rd inclined-plane 211 and the 4th inclined-plane 213 each respectively with the acutangulate surface angle of central longitudinal axis " X " shape, as directed called after B2, A1, B1, A2.

In particular case, shoulder 208 and 210 is designed such that surface angle A1 does not have surface angle A2 sharp-pointed, or can say A1>A2.When not wishing to be limited at any theory especially, the value of surface angle A1 is considered to closely relevant to the size that pin 140 is moved to from mounting point (position such as shown in Fig. 3) power that working position (position such as shown in Fig. 4) needs.The value of surface angle A2 is considered to closely relevant to the size that pin 140 is moved to from pre-installed position (such as the position shown in Fig. 2 A) power that mounting point (position such as shown in Fig. 3) needs.When A1 is greater than A2, applies extra power so that pin 140 is moved to working position from mounting point, and therefore can avoid the unexpected transformation from mounting point to working position.

Under specific circumstances, and in fig. 2 c, surface angle B1 is numerically greater than surface angle B2, in other words B1 > B2.When not wishing to be limited at any theory especially, the value of surface angle B1 is considered to closely relevant to the size that pin 140 is moved to from mounting point (position such as shown in Fig. 3) power that pre-installed position (such as the position shown in Fig. 2 A) needs.The value of surface angle B2 is considered to closely relevant to the size that pin 140 is moved to from working position (position such as shown in Fig. 4) power that mounting point (position such as shown in Fig. 3) needs.When B1 is greater than B2, needs to apply extra power and be back to mounting point to be moved from working position by pin 140, and therefore can avoid the unexpected transformation being back to mounting point from working position.

In a particular embodiment, and as illustrated illustratively in Fig. 2 C, the surface angle A1 be formed between the second inclined-plane 209 and central longitudinal axis X generally equals to be formed in the surface angle B1 between the 3rd inclined-plane 211 and central longitudinal axis X.Therefore, the benefit of this design is at least to cross the first neck and pushes away degree of difficulty or the easy degree that the power needed respectively with pull-up pin 140 has same levels for 215 times.In addition, pin 140 is further reduced relative to the unexpected of packing ring 120 or unwanted movement.

In a particular embodiment, any one position that pin 140 is positioned in mounting point, working position and pre-installed position can axial-rotation.Especially, smooth, the cylinder-shaped body of the position changed pin 140 is set to have the girth from the head 202 of pin 140 to pin.This makes the axial motion through packing ring 120 restrained, also makes pin 140 freely rotate in packing ring 120 simultaneously.Because the misalignment possibility between pin 140 and packing ring 120 can reduce effectively, be therefore easy to use.

In one or more embodiments, as previously mentioned disclosed the utility model provide pin-with-gasket type fastening piece, this fastening piece is considered to have superiority, and wherein can obtain relatively better determinacy, reliability and convenience in different operating position.But, those skilled in the art will from above-mentioned discussion, and easily recognize from accompanying drawing and claim, when not deviating from the utility model true spirit and fair scope of the present utility model defined by the following claims, multiple change can be made, modifications and variations.
